From time to time, people ask me how to “cut edges” in AC3D since the way AC3D handles edges is a bit different than other programs. Usually, I use the Divide Loop plug-in which is normally the fastest, easiest way to go. But, every now and then you get an edge that isn’t well suited for Divide Loop. In these cases, I use a combination of Insert Vertex and Slice Surface.

This video shows you how:

A QUICK SIDE NOTE: It is much faster to use the hotkeys (ctrl+shift+I and ctrl+shift+L) than it is to use the menus… the whole process can be completed in only a few seconds if you use the hotkeys. However, for the sake of clarity, I use the menus in the video so you can actually see what I’m doing. 🙂

The tiny little 320×240 render of the plasma for the POV-Ray tutorial was a bit hard to see, so I did a render in 1920 x 1080 resolution for those of you interested in seeing the details. It’s still a bit compressed, but the image is a lot clearer. You’ll find it here: download the video.

Autodesk has a fun quiz on their site called the Fake or Foto test. In the quiz, you have to look at each image, and guess whether it is real or a render. Surprisingly, I aced it the very first time!

After I took the quiz, I went back and documented all the things that made me think a particular image was real or fake. That way I could see what it was that clued me so that I might improve my own work. In almost all cases, it wasn’t that the CG images were obviously wrong in any way, it was simply that the real images had more “detail” in them.

For years, the limitation has been what the software could do, but I’m not so sure that’s true anymore. In games especially, production costs have gone up as graphics have become more realistic simply because making detailed images is very time consuming. The relationship between time, money and graphics detail is linear. The problem, of course, is that neither time nor money are infinite. Limited budget means limited production cycles, which means limited time to spend adding things like scratches, scrapes and nose hairs. Eventually, we’ll reach a point where we can’t add more detail not because we’re out of RAM–we can’t add more detail because we’re out of time! Truthfully, I think we’re on the horizon of that already.

While I’m certain that there are still numerous improvements to be made in traditionally researched areas such as lighting, I think technological improvements to workflow have more potential to improve the quality of computer graphics in the near future than virtually any other area. Automated procedural geometry, better methodologies and tools that allow for less restrictive workflow patterns–such as recent advancements in re-topology interfaces–can allow us to complete the same job in less time and with far less effort. We know the artists and software can do it; now we need to make it practical.

For the curious, here are my impressions from the Autodesk quiz:

Hi, I'm Lisa and I make arcade games. In the games industry, the first
question everyone always asks is "are you an artist or an engineer?" Consider me an engineer who likes to color. :) I love code. I love art. And I especially love code that makes art.
